Legendary investor George Soros is backing TruMid, a hot new bond-trading startup.

The billionaire's Soros Fund Management has invested in the company, according to people familiar with the matter. It isn't clear how much Soros is investing.

The investment represents a coup for the firm, which was set up late last year and officially launched on April 29 as an electronic trading marketplace for corporate bonds.

Michael Vachon, an adviser to the chairman at Soros Fund Management, and TruMid chief marketing officer Tim Reed each declined to comment on the investment.

TruMid started out trading high-yield and distressed bonds, and it added investment-grade bonds to its service earlier this month. It plans to launch credit default swap trading in the fourth quarter.

Trading is focused on 10-minute periods called swarms, with the idea being that having small windows of trading focuses liquidity in specific periods of time.

The firm was set up by Ronnie Mateo, who previously worked at inter-dealer broker Trinity Brokers, and has added numerous well-known Wall Street traders to its ranks since its formation.

Trading at TruMid is focused around "swarms."
They include Mike Sobel, a former head of high-yield bond trading at Lehman Brothers and Barclays, and Mike Martinic, who previously ran quantitative and fundamental credit trading for Citadel Asset Management.

While Reed at TruMid declined to comment on an investment, he did shed some light on TruMid's development since launch.

The platform has 182 clients signed up and onboarded to the platform, he said, made up of 24 dealers, 116 hedge funds and 42 so-called real-money investors. The platform has another 370 accounts in the process of being onboarded.

The platform has traded over $2 billion worth of high-yield and distressed bonds since launch, he added.
